Table 4 Responsiveness

From: Reliability, validity and responsiveness of the German self-reported foot and ankle score (SEFAS) in patients with foot or ankle surgery

  Responsiveness MID

SEFAS pain 52.06 (19.25) 29.37 (23.47) 22.69 (22.82) 1.06 0.99 4.97 213

  1. Responsiveness of the SEFAS showing mean changes, effect size and minimal important difference demonstrating minimal detectable change and standard error of measurement
  2. lof = limitation of function, o = others, SD = standard deviation, ES = effect size, SRM = standardized response means, MID = minimal important difference, MDC = minimal detectable change, SEM = standard error of measurement
